이하, 첨부된 도면을 참조하여, 본 발명에 따른 골드 안료에 관하여 상세히 설명하기로 한다.
Hereinafter, the gold pigment according to the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명의 실시예에 따른 골드 안료를 개략적으로 나타낸 것이다.3 is a schematic view of a gold pigment according to an embodiment of the present invention.

도 3을 참조하면, 본 발명의 실시예에 따른 골드 안료는 기재(100), 제1 피복층(310), 제2 피복층(320), 제3 피복층(330), 제4 피복층(340) 및 제5 피복층(350)을 포함한다. 3, a gold pigment according to an embodiment of the present invention includes a substrate 100, a first coating layer 310, a second coating layer 320, a third coating layer 330, a fourth coating layer 340, 5 coating layer (350).

피복층들(310 ~ 350)은 각각 대략 0.5㎛ 이하의 두께로 형성되며, 각각 60~90℃에서 형성될 수 있다. The coating layers 310 to 350 are each formed to a thickness of about 0.5 占 퐉 or less and can be formed at 60 to 90 占 폚, respectively.

제1 내지 제5 피복층(310 ~ 350)은 그 순서대로 1회만 형성될 수 있으며, 필요에 따라서는 그 순서대로 2회 이상 반복 형성될 수 있다. 아울러, 각각의 피복층 사이에는 추가의 피복층이 더 형성될 수 있으며, 제5 피복층(350), 즉 최상부 피복층 상에는 내후성 향상 등을 목적으로 보호 피복층이 더 형성될 수 있다. The first to fifth coating layers 310 to 350 may be formed only once in that order, and may be formed repeatedly in the order of two or more times, if necessary. In addition, an additional coating layer may be further formed between the respective coating layers, and a protective coating layer may be further formed on the fifth coating layer 350, that is, the uppermost coating layer for the purpose of improving weather resistance or the like.

기재(300)는 천연 운모, 합성 운모, 글래스 플레이크(Glass Flake), 알루미나 플레이크(Alumina Flake) 등으로 형성될 수 있다. 기재(300)는 일반적으로 입자 크기가 대략 5~600㎛ 정도인 소판 기재를 이용할 수 있으나, 반드시 이에 제한되는 것은 아니고 공지된 다양한 기재를 이용할 수 있다. The substrate 300 may be formed of natural mica, synthetic mica, glass flake, alumina flake, or the like. The substrate 300 may generally be a plate substrate having a particle size of about 5 to 600 mu m, but it is not necessarily limited thereto and various known substrates can be used.

제1 피복층(310)은 기재(300) 표면에 형성되며, 굴절률이 1.8 초과인 금속산화물을 포함한다. 제1 피복층(210)은 검은색 바탕 하에서 골드 컬러를 띄는 파우더로, 기본적인 색상을 결정하는 역할을 한다.
The first coating layer 310 is formed on the surface of the substrate 300 and includes a metal oxide having a refractive index of more than 1.8. The first coating layer 210 is a powder having a gold color under a black background and serves to determine a basic color.

이때, 제1 피복층은 TiO2만으로 대략 100~200nm 두께로 형성될 수 있다. TiO2는 루틸(Rutile) 또는 아나타제(Anatase) 구조를 가질 수 있으며, 루틸 구조를 가지는 것이 보다 바람직하다. 루틸 구조의 TiO2의 경우, 광택 및 안정성이 보다 우수한 장점이 있다. 이러한 루틸 구조의 TiO2 피복층은 SnCl4와 같은 주석화합물로 기재 표면을 전처리한 후, TiCl4 등을 이용하여 TiO2를 피복함으로써 형성될 수 있다. At this time, the first coating layer may be formed to have a thickness of about 100 to 200 nm with only TiO 2 . TiO 2 may have a rutile or an anatase structure, and more preferably a rutile structure. In the case of the rutile-structured TiO 2 , there is an advantage that the gloss and the stability are more excellent. The rutile TiO 2 coating layer can be formed by pretreating the substrate surface with a tin compound such as SnCl 4 and then coating TiO 2 with TiCl 4 or the like.

제1 피복층(310) 및 후술하는 제4 피복층(340)을 TiO2로 형성할 경우, 제1 피복층(310) 및 제4 피복층(340)은 pH 3 이하의 강산성 조건 하에서 TiCl4로부터 형성될 수 있다.
When the first coating layer 310 and the fourth coating layer 340 described later are formed of TiO 2 , the first coating layer 310 and the fourth coating layer 340 may be formed from TiCl 4 under strong acidic conditions of pH 3 or less have.

제2 피복층(320)은 제1 피복층(310) 상에 형성되며, MnO와 같은 망간을 함유하는 산화물을 포함한다. 이러한 망간을 함유하는 산화물은 MnO, MnO2를 제시할 수 있고, 이들은 흑갈색을 띄고 있으며, 이들 중 어느 1종을 이용하거나 또는 2종 모두를 혼용할 수 있다. The second coating layer 320 is formed on the first coating layer 310 and includes an oxide containing manganese such as MnO. Such manganese-containing oxides can exhibit MnO and MnO 2 , and they are blackish brown. Any one of them may be used, or both of them may be used in combination.

백색의 TiO2 피복층과 적색의 Fe2O3 피복층에 의해 구현되는 골드 색상의 경우 다소 붉은 빛을 띄나, 본 발명에서와 같이 백색의 TiO2 피복층(예를 들어 도 3의 310)와 적색의 Fe2O3(예를 들어 도 3의 350) 사이에 MnO와 같은 Mn 함유 산화물 피복층(예를 들어 도 3의 320)이 포함되는 경우 종래의 붉은 빛을 띄는 골드 색상에서 붉은 빛을 어느 정도 제거함으로써 골드 색상을 보다 정확히 나타낼 수 있다. The gold color realized by the white TiO 2 coating layer and the red Fe 2 O 3 coating layer is somewhat reddish. However, as in the present invention, a white TiO 2 coating layer (for example, 310 in FIG. 3) and a red Fe When the Mn-containing oxide covering layer (for example, 320 in FIG. 3) such as MnO is included between 2 O 3 (for example, 350 in FIG. 3), the red light is removed to some extent in the conventional red- Gold color can be displayed more accurately.

망간 함유 산화물을 포함하는 제2 피복층(320)은 pH 6~8의 중성 조건 하에서 MnCl2로부터 형성될 수 있다.
The second coating layer 320 comprising the manganese-containing oxide may be formed from MnCl 2 under neutral conditions of pH 6-8.

제3 피복층(330)은 제2 피복층(320) 상에 대략 10~200nm 두께로 형성되며, 굴절률 1.8 이하인 무색 금속산화물을 포함한다. 이러한 제3 피복층(230)은 저굴절층으로서, 고굴절층(예를 들어 도 3의 310)과 고굴절층(예를 들어 도 3의 340, 350) 사이에 위치하여 광학적 간섭 구조를 형성함으로써, 본 발명에 따른 골드 안료가 간섭 안료로 작용할 수 있도록 한다. The third coating layer 330 is formed on the second coating layer 320 to have a thickness of about 10 to 200 nm and includes a colorless metal oxide having a refractive index of 1.8 or less. The third coating layer 230 is a low refractive layer and is positioned between the high refractive index layer 310 and the high refractive index layer 340, for example, 340 and 350 of FIG. 3 to form an optical interference structure. So that the gold pigment according to the invention can act as an interference pigment.

이러한 굴절률 1.8 이하인 무색 금속산화물은 SiO2, MgO·SiO2, 및 Al2O3 중에서 1종 이상을 포함할 수 있다. The colorless metal oxide having a refractive index of 1.8 or less may include at least one of SiO 2 , MgO · SiO 2 , and Al 2 O 3 .

제4 피복층(340)은 제3 피복층(330) 상에 형성되며, 굴절률이 1.8 초과인 금속산화물을 포함한다. 이러한 제4 피복층(340)은 백색 금속산화물로 형성될 수 있고, 예를 들어, TiO2 피복층으로 형성될 수 있다. The fourth coating layer 340 is formed on the third coating layer 330 and includes a metal oxide having a refractive index of more than 1.8. The fourth coating layer 340 may be formed of a white metal oxide, for example, a TiO 2 coating layer.

제5 피복층(350)은 제4 피복층(340) 상에 형성되며, Fe2O3를 포함한다.The fifth coating layer 350 is formed on the fourth coating layer 340 and includes Fe 2 O 3 .

이러한 Fe2O3는 굴절률 1.8을 초과하는 고굴절의 붉은색 금속산화물에 해당한다. Such Fe 2 O 3 corresponds to a high-refraction red metal oxide having a refractive index exceeding 1.8.

제5 피복층은 pH 2~4의 산성 조건 하에서 FeCl3 등과 같은 철 함유 화합물로부터 형성될 수 있다.
The fifth coating layer may be formed from an iron-containing compound such as FeCl 3 under an acidic condition of pH 2 to 4.

제1 내지 제5 피복층(310 ~ 350) 중에서 망간 산화물을 포함하는 제2 피복층(320)의 두께는 일정 두께일 때 바람직한 효과를 얻을 수 있다. 망간 산화물의 두께가 너무 얇으면 붉은 톤이 저감 효과가 불충분할 수 있고 너무 두꺼우면 광택 등이 저하될 수 있기 때문이다. 보다 바람직하게 제2 피복층(320)은 기재 중량을 100중량부라 할 때, 상기 제2 피복층의 함량이 0.1~10중량부가 될 수 있으며, 이때 제2 피복층의 두께가 0.1~20nm가 될 수 있다.
A preferable effect can be obtained when the thickness of the second coating layer 320 including the manganese oxide in the first to fifth coating layers 310 to 350 is a certain thickness. If the thickness of the manganese oxide is too thin, the redness may be inadequate, and if it is too thick, the gloss and the like may be deteriorated. More preferably, when the weight of the substrate is 100 parts by weight, the content of the second coating layer may be 0.1 to 10 parts by weight, and the thickness of the second coating layer may be 0.1 to 20 nm.

본 발명의 골드 안료는 도 2의 5개 피복층을 모두 포함하여야만 하는 것은 아니며, 아래와 같은 3개 이상의 피복층을 포함하는 조건이라면 모두 본 발명의 범주에 포함된다. The gold pigment of the present invention does not have to include all of the five coating layers shown in Fig. 2, and all the conditions including three or more coating layers as described below are included in the scope of the present invention.

즉, 본 발명의 골드 안료는 기재 상에 TiO2를 포함하는 피복층 및 Fe2O3를 포함하는 피복층을 포함하는 다층의 피복층이 형성된 구조를 가지나, Fe2O3를 포함하는 피복층은 TiO2를 포함하는 피복층보다 외측에 있고, Fe2O3를 포함하는 피복층과 TiO2를 포함하는 피복층 사이에 망간 함유 산화물을 포함하는 피복층이 형성되어 있는 구조를 갖는 것이라면 모두 적용될 수 있다.
That is, the coated layer to a gold pigment according to the present invention comprises a gajina a structure in which a multi-layer coating comprising a coating layer comprising a coating layer and Fe 2 O 3 containing TiO 2 on a substrate formed, Fe 2 O 3 is TiO 2 And a coating layer containing manganese-containing oxides is formed between the coating layer containing Fe 2 O 3 and the coating layer containing TiO 2 .
